Nouveau saxhorn basse. Nominal pitch: C / B♭.

Technical description: Brass; final section of bell flare fitted to bell-pipe with flanged joint and secured with four small screws with cross-cut heads, the bell mouth can to rotated to point in any desired direction. The windway runs mouthpipe - m.t.s. - 1 - 2 - 3 - 4 - 5 - 6 - 6 - 5 - 4 - 3 - 2 - 1 - bell; operating any valve returns the windway to that valve via a short loop with a valve tuning-slide and cuts out all further valves from the windway. For use in B♭, the instrument would require a main tuning-slide extension piece or an alternative tuning-slide. Valve type: 6 Périnet-type independent piston valves, in usual two groups of three. Bottom-sprung; alignment by key on piston. Bottom caps have no vent hole; instead each valve has an air release passage running from bottom to top on the outside of the casing. Repair History: One of the valve pistons is a replacement (1991).
